How to use it
A quick estimate, without the spreadsheet.
Inputs and units
Enter today’s amount, an assumed average annual inflation percentage and years.
Formula
Equivalent future cost = current amount × (1 + inflation / 100)^years.
Worked example
$1,000 at 3% inflation for one year has an equivalent future cost of $1,030.
Assumptions and limitations
Uses a constant rate supplied by you, not historical CPI data. It estimates future cost rather than the future purchasing power of a fixed cash balance.
